Does it really matter if I use (say) rose fertiliser on
my beans, or on my spuds?

Different fertilisers have a different balance of the main nutrients
depending on whether you want to encourage healthy foliage or promote
flowering. Rose fertiliser is designed to promote flowering, so could be
a reasonable choice for beans, but might not be what you're aiming for
on with potatoes.
